『一』What does blockchain mean?

Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

1. Blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and non-forgeable. Distributed ledger.

2. Blockchain is an important concept of Bitcoin. It is essentially a disintermediated database. At the same time, as the underlying technology of Bitcoin, it is a series of related cryptographic methods. data block.

(1) What does 3 o’clock blockchain mean? Extended reading:

1. The Bitcoin peer-to-peer network stores all transaction history In "blockchain". The blockchain continues to lengthen, and once new blocks are added to the blockchain, they cannot be removed.

2. The blockchain shared value system was first imitated by many cryptocurrencies, and improvements were made in proof of work and algorithms, such as the use of proof of equity and SCrypt algorithms.

3. The blockchain is actually a group of dispersed user nodes and a distributed database composed of all participants. It is a record of all Bitcoin transaction history.

4. Blockchain technology will be applied to credit reporting, transaction security and information security in the financial industry. Blockchain can form point-to-point digital value transfer in finance, thus improving the security of transmission and transactions.

『二』What is the concept of blockchain

Concept: Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

The essence of the blockchain is a distributed public ledger. Anyone can verify this ledger, but no single user can control it. Participants in a blockchain system jointly maintain a ledger: it can only be modified according to strict rules and consensus.

The development of blockchain has gone through three stages:

1. Incubation period: 2009-2012, the economic form was dominated by Bitcoin and its industrial ecology.

2. Embryonic period: The period is from 2012 to 2015. Blockchain entered the public eye with Bitcoin, new wallet payment and remittance companies appeared, and the blockchain economy spread to the financial field. The underlying technology of blockchain continues to innovate. Blockchain technology is divorced from the Bitcoin system.

3. Development period: In 2016, industry applications began to be explored, and a large number of blockchain startups emerged. The popularity of ICO in 2017 brought unprecedented attention to blockchain.

(2) What does 3 o’clock blockchain mean? Extended reading:

Three special points of three blockchains: < /p>

1. The core idea of ​​blockchain is decentralization: in the blockchain systemIn , the rights and obligations between any nodes are equal, and all nodes have the ability to vote with computing power, thus ensuring that the recognized result is the result recognized by more than half of the nodes. Even if it suffers a severe hacker attack, as long as the number of nodes controlled by the hacker does not exceed half of the total number of global nodes, the system will still be able to operate normally and the data will not be tampered with.

2. The biggest disruption of blockchain lies in the establishment of credit: in theory, blockchain technology can make WeChat Pay and Alipay no longer valuable. The Economist made a vivid metaphor for blockchain: simply put, it is “a machine that creates trust.” Blockchain allows people to collaborate without trusting each other and without a neutral central authority. Combating counterfeit currency and financial fraud will no longer be needed in the future.

3. The collective maintenance of blockchain can reduce costs: In a centralized network system, the maintenance and operation of the system rely on the operation, maintenance and operation of platforms such as data centers, and the cost of failure cannot be omitted. Anyone can participate in the nodes of the blockchain. While participating in the recording, each node also verifies the correctness of the recording results of other nodes, which improves maintenance efficiency and reduces costs.

In one sentence, blockchain touches money, trust and power, which are the fundamental foundations on which human beings rely for survival.

『三』 In order to seize this trend, Tong Liya and Gao Xiaosong joined the "3 O'clock Sleepless" group, but Han Geng was kicked out

Recently, a "3 O'clock Sleepless" blockchain "Group" (hereinafter referred to as the 3:00 Sleepless Group) has become popular in the investment circle!

According to China Entrepreneur Magazine, big names in the investment circle such as Sequoia Capital Shen Nanpeng, 360 Chairman Zhou Hongyi, angel investors Cai Wensheng, Xue Manzi, etc. are all in this group, and even Gao Xiaosong, Tong Liya , Lin Yoona, Han Geng and other stars.

This WeChat group, created on February 11, reached the upper limit of 500 members in less than a day. During the Spring Festival, it is said that the total amount of red envelopes in this group reached one million. However, this is not the main motivation for celebrities and big shots to join the group. It is even forbidden to publish information such as currency speculation and ICO in this group. People in the group mainly learn about the application prospects of blockchain technology.

I noticed that according to the definition of "China's Blockchain Technology and Application Development White Paper" issued by the Ministry of Industry and Information Technology, blockchain is a computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Innovative application models in the Internet era.

Blockchain technology is considered to be a disruptive innovation in computing models after mainframes, personal computers, and the Internet, and is likely to cause a new technological innovation and industrial change on a global scale.

Today, with the price of Bitcoin “cutting in half” from its peak, and the strict supervision of countries such as China, “The craze for "virtual currency" has begun to dissipate. However, as the underlying technology, blockchain is expected to be widely used in finance, supply chain management, manufacturing, Internet of Things and other fields in the future.

Zeng 7 days in the group Red envelopes distributed over one million

"3 O'clock Sleepless Blockchain Group" was originally founded by Yuhong on February 11. Yuhong was previously the main person in charge of 360 Games and is now the founder of SEEU& QYGAME People, who once launched the large-scale online game "Basic World" based on blockchain.

Since the group was first established at three o'clock in the morning, it was named 3 O'clock Sleepless Blockchain Group.

In this WeChat group, known as the first useful group for blockchain, there are Sequoia Capital Shen Nanpeng, 360 Chairman Zhou Hongyi, angel investors Cai Wensheng, Xue Manzi, Fenbushi Capital Partner Shen Bo, and even stars such as Gao Xiaosong, Tong Liya, Lin Yuner, Han Geng.

Xue Manzi, Li Xiaolai, Chen Weixing, Shuai Chu, etc. are the earliest participants in the blockchain. Xue Manzi invested in Quantum Chain , Bytom Chain, Mo Chain. Li Xiaolai is the first person in China to invest in Bitcoin and Ethereum. Chen Weixing also has his own fund and has invested in Huobi, Binance, Tron and other projects. Shuaichu is the founder of Quantum Chain.

What’s interesting is that the person who received the warmest welcome among those who joined the group was not the industry boss, but the film and television star Tong Liya. It is said that after Tong Liya was added to the group, there were more messages welcoming her to join. There are hundreds of entries. Tong Liya said that she is still a beginner in blockchain and hopes to learn more, and attached a big red envelope of 8,000 yuan.

Some inactive people in this group will be Kick away, such as Han Geng, No. 1 Matchmaker founder Mu Yan, Meitu CEO Wu Xinhong, etc. Those who stay in the group often engage in intense "mutual hostility" discussions, and there are also some new members who are thirsty for knowledge and quickly absorb the blockchain fresh knowledge.

On February 24, Chen Weixing in the group and Zhu Xiaohu, managing director of Jinshajiang Venture Capital, had a "mutual fight" around the blockchain.

The cause of the matter is that Zhu Xiaohu forwarded an article about blockchain in his circle of friends and said not to include him in various 3 o'clock groups. Some outlets would rather miss out, and some money would rather not be made, otherwise the festival will be ruined.

This statement immediately aroused Chen Weixing's refutation. Chen Weixing asked, is the method of cutting leeks in equity investment more advanced than the currency circle? Is the bubble in the entire blockchain industry as high as the global stock market bubble? Zhu Xiaohu responded, ICO, a model that tests human nature, has never been successful.

Don’t talk about currency speculation, just talk about blockchain

Yuhong and the first industry leaders to join the group, Xue Manzi, Chen Weixing, etc., jointly set rules in the group: posting in the group is strictly prohibited News about currency speculation, ICO, etc. Therefore, the main topic of group chat is the application of blockchain technology.

Guo Hongcai is a well-known figure in the currency circle. He doesn’t know much about blockchain technology, but he became a rich man through currency speculation. He was kicked out of the group for the second time because he said in the group, "I'm here to make money anyway. Talking about technology is really meaningless... The biggest application of blockchain is currency speculation." After being kicked out, Guo Hongcai was unconvinced and sulked in another group, "They never talk about making money, they are too vain."

China has always been at the forefront of regulating virtual currency speculation.

In September last year, China completely banned the domestic Bitcoin trading platform business. This regulation also has an impact on global Bitcoin transactions.

On February 5 this year, the People’s Daily published another article discussing “currency speculation” and believed that all countries should strengthen coordinated supervision to prevent systemic risks.

People's Daily stated that in recent times, various conferences and exchange activities with the themes of blockchain, digital assets, and virtual currencies have emerged one after another, and crazes such as "coin speculation" and "disguised ICO" have also emerged one after another. Some people join the "coin speculators", hoping to obtain huge returns through short-term speculation. Since blockchain and virtual currencies can transcend national boundaries, countries should strengthen coordinated supervision to prevent virtual currency transactions from causing systemic financial risks.

This is exactly what it is:

The virtual currency is booming,

and it is a series of sudden rises and sudden falls.

Beat the drum and spread the flowers, blow the big bubble,

There is an urgent need to regulate the cloud.

Blockchain has broad application prospects

According to the white paper of the Ministry of Industry and Information Technology, blockchain technology originated from a scholar with the pseudonym "Satoshi Nakamoto" published in 2008 The foundational paper "Bitcoin: A Peer-to-Peer Electronic Cash System".

In a narrow sense, blockchain is a chain data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be non-tamperable and Unforgeable distributed ledger.

Currently, blockchain technology is hailed by many large organizations as a major breakthrough technology that will completely change the way business and even organizations operate.

The widespread application of blockchain technology can enable "decentralization" to be realized at low cost.

When we send an email, what the other party receives is actually a copy of the email, which allows the information to be spread quickly. However, this approach cannot be replicated in applications in finance and other fields. For example, when you pay 100 yuan to the other party, you cannot copy and paste the 100 yuan currency in your hand to the other party.

Therefore, in today's society, transactions involving cash, securities, intellectual property rights, patents, carbon emission quotas, etc. must be solved with the help of a huge central institution (bank, third-party payment platform, etc.) Trust issues will increase transaction costs and slow down transactions. For example, we can send an email in a minute, but a transfer within the same city may take several days. Transferring funds from one country to another comes with high fees.

Canadian blockchain expert Don Tapscott believes that blockchain technology will change the world and make trust-building technology simple and easy to understand. He said that the popularity of blockchain technology means that we may no longer need a powerful central institution as a credit medium in the future. This is the next generation of the Internet, one that has the potential to transform our money, trade, government, and society.

『四』What does blockchain mean?

1. Blockchain is a distributed data storage, point-to-point transmission, and consensus mechanism. , encryption algorithms and other new application models of computer technology. Blockchain is an important concept of Bitcoin. It is essentially a decentralized database. As the underlying technology of Bitcoin, it is a series of data blocks generated using cryptographic methods. Each The data block contains information about a batch of Bitcoin network transactions, which is used to verify the validity of the information (anti-counterfeiting) and generate the next guess block.

2. In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao.

3. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period and write down his recorded content. ledger, and send the ledger contents to all other people in the system during this period.Make a backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.

『五』What does blockchain mean?

『Lu』 What does blockchain mean in a popular way?

Question 1: What is blockchain? Can you explain the principle of 10-point blockchain in plain language: decentralized distributed accounting system
The core of blockchain technology is the joint maintenance of all currently participating nodes. Transactions and databases, which make transactions based on cryptographic principles rather than trust, so that any two parties who reach an agreement can directly conduct payment transactions without the participation of a third party.
?
Technically speaking, a block is a data structure that records transactions, reflecting the flow of funds for a transaction. The blocks of transactions that have been reached in the system are connected together to form a main chain, and all nodes participating in the calculation record the main chain or part of the main chain. A block contains the following three parts: transaction information, hash hash formed by the previous block, and random number. Transaction information is the task data carried by the block, specifically including the private keys of both parties to the transaction, the number of transactions, the digital signature of electronic currency, etc.; the hash formed by the previous block is used to connect the blocks to realize the past The order of transactions; random numbers are the core of transaction completion. All miner nodes compete to calculate the answer to the random number. The node that gets the answer the fastest generates a new block and broadcasts it to all nodes for update, thus completing a transaction.
1.1 What is Blockchain
Blockchain (BlockChain) refers to a technical solution that collectively maintains a reliable database through decentralization and trustlessness. This technical solution mainly allows any number of nodes participating in the system to associate and generate a series of data blocks (blocks) using cryptographic methods. Each data block contains all the information exchange data of the system within a certain period of time, and generates The data fingerprint is used to verify the validity of its information and chain to the next database block.
?
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. Behind all systems there is a database, which is a big ledger. Then who will keep this ledger becomes very important. At present, it is whoever owns the system who keeps the accounts. Each bank’s account books are kept by each bank, and Alipay’s account books are kept by Alibaba. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are new transaction data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write the recorded content to the ledger, and Send the contents of the ledger during this period to all other people in the system for backup. In this way, everyone in the system has a complete ledger. Therefore, this data becomes very safe. Tamper needs to modify more than half of the system at the same timeNode data can truly tamper with data. Such tampering would be extremely costly, making it nearly impossible. For example, Bitcoin has been running for more than 7 years. Countless hackers around the world have tried to attack Bitcoin, but so far there have been no transaction errors. It can be considered that the Bitcoin blockchain has been proven to be a safe and reliable system.
?
1.2 Why is there blockchain innovation?
Human beings need to communicate during their activities, and communication is based on information. In the past, information circulation was not convenient enough to satisfy market participants. There is a demand for information, so intermediaries and centers are born. This centralized system has problems such as high cost, low efficiency, value dispersion, "information islands" and insecure data storage. However, due to technical and environmental factors, this system continued to operate for many years until the emergence of the Internet. The starting point of the first generation of the Internet is the TCP/IP protocol, which is an open code that implements a unified format for peer-to-peer transmission of information by all nodes on the network, and brings the basic values ​​of freedom and equality required by a global unified market into programmed, protocol-based, and reliably Execution. The Internet eliminates low-value, high-cost intermediate chains and achieves low-cost and high-efficiency global information transmission in a decentralized manner.
?
However, the first generation of the Internet did not solve the problem of information credibility. Activities that can be decentralized on the Internet must be activities that do not require credit endorsement, and activities that require credit guarantee must be activities involving centralized third-party intermediaries. Therefore, Internet technology that cannot establish global credit has encountered great obstacles in its progress - people cannot participate in any value exchange activities on the Internet in a decentralized manner. To realize value exchange, people still need third-party intermediaries based on credit (such as banks, clearing agencies, exchanges). The global centralized credit system still has problems such as high operating costs, low efficiency, and vulnerability to attacks and damage. For example, each country's legal currency has different credit values ​​and incompatible clearing systems, which adds a lot of cost to global trade.
?
Therefore, what the second generation Internet must break through is: how to establish global credit in a decentralized manner? Let...>>

Question 2: What is blockchain? What does it mean in layman’s terms? What is China’s attitude towards blockchain? What can blockchain do? Blockchain, a great technology that accompanied the birth of Bitcoin, is currently being used in the financial field to significantly reduce transaction costs and improve efficiency, which is enough to excite Wall Street. However, this is just the tip of the iceberg. Its potential applications are very broad and will subvert every aspect of our lives in the future.
Blockchain is an important concept of Bitcoin. It is essentially a decentralized database and serves as the underlying technology of Bitcoin. One of the most basic characteristics of Bitcoin is decentralization. In recent months, financial giants have gradually begun to pay attention toBitcoin’s technology is used in non-monetary fields, such as stock trading, election voting, etc. (1) Art Industry
Artists can use blockchain technology to declare ownership and issue numberable, 100% edition works in digital form for any type of artwork. It even includes a marketplace where artists can buy and sell through their website without the need for any intermediary services.
(2), Real estate industry
Use blockchain technology to solve various problems faced by everyone involved in real estate, including the naming process, land registration, agency intermediaries, etc.
(3), Insurance Industry
The financial industry has always been the most sensitive to advanced technology. Traditional banking and securities industry giants have been involved in the booming blockchain venture capital investment since 2014, with total global investment reaching US$1 billion within two years.
(4) P2P wallet
Personal assets can be traded through this P2P wallet in the future without going through any central institution, such as Bitcoin.
Most blockchains are in their infancy, mainly overseas. There are very few good domestic blockchain projects, so it is not recommended for any non-professionals to invest in blockchain projects. If you are very interested in blockchain technology and have a technical or financial background, it is recommended that you consider starting a business in this area. In terms of the blockchain protocol system, the lowest layer is the underlying technology of the blockchain, including the technical protocols of the blockchain, as well as some platform routing and basic algorithms; in the middle layer, some application interfaces and some credentials must be solved Issuance and verification, including some industry platform services, big data analysis, etc. This is a very rough classification, and there should be more detailed classifications; the top ones are some applications of blockchain, including finance Some applications and some applications in other aspects, the Internet of Things and so on.
Introduction to Bubi Blockchain
Bubi Blockchain has been focusing on the research and development and innovation of blockchain technology and products since its establishment. It has a number of core technologies and has achieved substantial results in many aspects. Radical innovation has resulted in a number of core technological achievements, such as: mathematically provable distributed consensus technology, fast large-scale ledger access technology, multi-chain general ledger technology that supports business expansion, and interconnection technology between heterogeneous blockchains. wait. On April 25, "Gege Points" introduced the concept of blockchain into the points system, jointly opened it up with multiple parties, issued and redeemed points, and promoted the circulation of points. Each cooperative institution can jointly participate in transaction verification, ledger storage, and real-time settlement; the third-party payment platform of the enterprise points issuer makes the entry and exit of points more flexible. Bubi has developed its own basic blockchain service platform, which has been applied in equity, supply chain, points, credit and other fields. Bubi has been committed to building an open value circulation network with decentralized trust as the core, allowing digital assets to flow freely.
Blockchain is simpleThe understanding is that it is a technology at the bottom of Bitcoin, which is a peer-to-peer electronic cash system that can realize peer-to-peer value delivery. We should distinguish between concepts such as Bitcoin, Bitcoin blockchain, blockchain and blockchain technology. In countries with relatively developed finance in the past, finance and blockchain technology have a long history, and the legislation of digital currencies and blockchain networks is also very important. With the advent of the financial era, large financial institutions are studying blockchain technology. They have their own teams and conceptual technologies. Slowly, banks in various regions are also participating in digital currency discussions. The application and support of this technology are not only that. The influence of blockchain on enterprises is also huge. For larger domestic enterprises, Bubi Blockchain is also used in various equity, supply chain, points and other fields. Major domestic financial institutions and enterprises have taken a fancy to the new industry. value, they have developed their own blockchain platforms, and blockchain has instantly become a new innovative industry in China. In terms of overseas internationalization, the United States has already obtained 15 blockchain patents at the end of last year compared to China. Blockchain financial applications are entering a new stage in an all-round way. Various applications will become more and more in-depth, and related changes will also become more and more profound. It has attracted more and more attention and will form a huge new trend... >>

Question 3: What is blockchain technology? What exactly is blockchain? What is blockchain? 1. Data blockchain is an important concept in the Bitcoin financial system. It records transaction record data on the entire Bitcoin network, and these data are shared by all Bitcoin nodes. Through the data block, we can query each transaction record. A look at the history of Bitcoin transactions. 2. Example: There are three persons A, B, and C. All funds of A and B are kept by C. And every financial transaction must be recorded by C. Now assume that A and B each have 1 million in custody of C. Then: A spends 80,000 yuan to B, then C's account book record will subtract 80,000 yuan from A's name, and add 80,000 yuan to B's name. If B transfers 50,000 yuan to A, C will add 50,000 yuan to A's name and subtract 50,000 yuan to B's name in the account book. A spends 50,000 yuan to B, then C's account book record will subtract 50,000 yuan from A's name, and add 50,000 yuan to B's name. 3. The role of the data blockchain is similar to that of C’s account record book. It records the user’s ownership of Bitcoin and the records of all users’ Bitcoin transactions. It’s just that this “account record book” is recorded by the mining software of every Bitcoin miner on the network. If a Bitcoin transaction is confirmed by the data blockchain, the relevant information will be recorded in the data blockchain. Bitcoin’s “account record book” is called the data blockchain. All data blockchains on the network form Bitcoin’s distributed network database system. 4. The essence of data blockchain technology is a decentralized and distributed structure of data storage, transmission and certification methods. It uses data blocks to replace the current Internet's dependence on central servers, so that all data changes or transaction items are recorded. On a cloud system,Theoretically, the self-certification of data in data transmission is realized. In a far-reaching sense, this transcends the traditional and conventional information verification paradigm that relies on the center and reduces the cost of establishing global "credit." This point-to-point verification will generate A "basic protocol" is a new form of distributed artificial intelligence that will establish a new interface and shared interface for human brain intelligence and machine intelligence.

Question 4: What is blockchain: This explanation of blockchain is more understandable. Blockchain refers to a technology that collectively maintains a reliable database through decentralization and trustlessness. plan.
In layman’s terms, blockchain technology refers to a way for all people to participate in accounting. There is a database behind all systems. You can think of the database as a big ledger. Then who will keep this ledger becomes very important. Currently, whoever owns the system keeps the accounts. Tencent keeps the accounts of WeChat, and Alibaba keeps the accounts of Taobao. But now in the blockchain system, everyone in the system has the opportunity to participate in accounting. If there are any data changes within a certain period of time, everyone in the system can do accounting. The system will judge the person who has the fastest and best accounting during this period, write his recorded content into the ledger, and record this Within a period of time, the contents of the ledger are sent to all other people in the system for backup. In this way, everyone in the system has a complete ledger. In this way, we call it blockchain technology.
Blockchain technology has become the darling of the financial community in China and has become a hot topic. Domestic Puyin Group has launched Puyin, a tea-based digital currency.

Question 5: Explain in an easy-to-understand manner what blockchain is. Blockchain can be understood as a database system in a sense. The development of blockchain can be divided into 1.0 and 2.0
1.0 is represented by Bitcoin, and its main application is virtual currency or digital currency application. The blockchain at this time can only be used for simple digital currency transactions.
2.0 is represented by the now popular ethereum (Ethereum) and the upcoming hyperledger. The blockchain at this stage can not only meet the corresponding digital currency transactions, but also use smart contracts to customize currency or asset transactions. If we use the database analogy, the emergence of smart contracts can be understood as allowing users to define functions or stored procedures in the database and call and execute them.
Different from traditional databases, the blockchain introduces consensus mechanism, incentive mechanism, p2p (network), hash and other specific elements, making it open, decentralized and non-tamperable. characteristic.

Question 6: What is blockchain? Is there any master who can explain it in layman’s terms? Blockchain is Bitcoin.The underlying technology is like a ledger that records all transaction records. It is decentralized. What is decentralization? For example, when you buy something on Taobao, you place an order and pay in Alipay. Alipay will not transfer the money to the seller until you receive the goods. Alipay is the third party in that center. Without it, it means decentralization, just like buying things offline. If you pay with one hand and get the goods with the other hand, there is no third party.
The blockchain itself is a series of cryptographically related data blocks generated.
Look carefully to see if it looks like a ledger. The pieces one by one are blocks, and connected together they are the blockchain.
Many companies are developing this technology, including ours, and its prospects are incredible. For details, you can go to our official website and hope to adopt it, thank you

Question 7: What is blockchain technology? What is blockchain? How to explain the concept of blockchain? People in each industry have different understandings, and relevant explanations are gradually emerging due to more and more real-life applications. With the popularization of this blockchain technology, the related results are getting bigger and bigger. If we want to understand this technology, we must have an in-depth understanding of reality.
In the past six months, the concept of blockchain has gradually become popular in China, and a blockchain whirlwind has taken off in the financial circle. Blockchain has attracted the attention and favor of more and more people in the industry due to its unique technical advantages. Blockchain technology, which is decentralized (or multi-centered), highly transparent, cannot be tampered with, and has no single point of failure, is entering the field of vision of financial institutions and enterprises. It has at least been used in digital currency, payment exchange, registration and settlement, Digital assets, traceability and anti-counterfeiting, supply chain, Internet of Things and many other fields have moved from theoretical discussions to practical applications.
"Blockchain" was first introduced with "Bitcoin" released in early 2009. Blockchain has become the basic protocol and technical application for the launch, recording, and circulation of Bitcoin. Although Bitcoin has been controversial since its inception and cannot even be regarded as a "currency" by governments and monetary authorities, the blockchain technology used in Bitcoin has been recognized by governments, including governments and monetary authorities. extensive attention.
Why has blockchain become a rapidly heating up hot technology and topic?
The most important of these may be that the launch of Bitcoin based on blockchain technology has opened up a new relationship with traditional society ( The exploration and attempt of brand-new technologies and rule systems such as Internet user identity verification, wealth confirmation, transaction records, notarization and verification, which have little connection with offline) and are fully applied in the online world (online), provide people with the opportunity to adapt to the Internet society. Development provides alternative paths and unlimited imagination.
Judging from its application in Bitcoin, blockchain is a set of new network blocks (BLOCK, also called communities) formed by combining encryption technology with the Internet. Bitcoin configuration, Internet user identity verification, and Bitcoin (value) confirmation formed by mining, BitcoinTransaction records, as well as extended encryption of Bitcoin cross-block flows (value transfer) (adding factors such as block and transaction time marks) registration and verification, block connection (Blockchain), Fully encrypted, mutually authenticated Internet protocol rules and accounting (Ledger) system. Precisely because Bitcoin is not a substitute for offline legal currency, but is issued and managed by non-legal currency authorities, mainly imitating the model of gold, and is completely new and decentralized protected and supported by basic Internet protocols and strict encryption technology. Internet currency (virtual currency) has thus formed a new set of currency rules and systems that are different from and not subject to real social laws, and can be bought, sold or exchanged with legal currency. It has been more than 8 years since Bitcoin was launched. There has been no record of funds or user information being stolen. Its security has been verified, and its efficiency and cost of fund settlement also have obvious advantages. This has made people's confidence in the blockchain technology used in Bitcoin continue to increase, and people have become more and more aware that although blockchain is a technology and protocol pioneered and applied by Bitcoin, the blockchain Chain is not the same as Bitcoin, and its application is by no means limited to Bitcoin. The application of blockchain can be decentralized or centralized; it can be a public chain model or a private chain model. Therefore, after Bitcoin, blockchain technology is also constantly developing and innovating, and constantly exploring new application fields, especially in the financial field.
The reason why blockchain is valued highly by more and more people is because the development and widespread application of the Internet have caused more and more economic exchanges and transaction activities to be conducted online, and the online world (or online world) society) is rapidly expanding, enriching and active, and online transactions must solve the efficiency and security protection issues of the parties' identity verification, value verification, transaction records, inspection and verification, etc., and require strict intermediaries and agreements (rules or constitutions). In this regard, traditional thinking and customary practices are to follow the development trajectory of the transfer of offline transactions to online and push the common rules and practices of the real (offline) society to the online (network) society. However, in practice, it is increasingly It is difficult to adapt to the needs of online transactions.
For example, for the identity verification of the parties, the natural choice is to use the information on the identity documents protected by the laws of various countries as the basis, and then add account or transaction passwords, as well as facial recognition, iris, fingerprints and other biometrics to conduct online transactions. Verification, but this method first makes the citizen identity information in the cross-border interconnected online world subject to the administrative jurisdiction of real society... >>

Question 8: Easy to understand Explain clearly what is blockchain. The English name of blockchain is Blockchain. Block literally means block, block, and chain means chain, chain. Therefore, together they are translated into blockchain.
1. Use cryptography technology toEncryption and decryption are performed so that records cannot be tampered with. Common blockchain encryption methods include hash algorithm, RSA algorithm, elliptic curve algorithm, etc.;
2. The huge amount of calculation needs to be supported by a reasonable reward mechanism. Because every transaction must be recorded, Bitcoin’s blockchain has more than 60 gigabytes so far. Every new transaction requires confirmation of the information related to the trading account to ensure that the transaction is valid. The huge amount of calculation requires a computer with powerful computing power to complete.
In order to encourage the participation of powerful computing power, Bitcoin provides two rewards: one is to issue a certain number of Bitcoins to these computers every day; instead, all transfer fees are awarded to these computers. (The technical term for these computers is "mining machines", and the people who hold the mining machines are called "miners".)
Biying China is working hard on the digitization of assets and has launched the digital currency crowdfunding platform Biying China.

Question 9: What is the so-called "blockchain"? Blockchain itself is a tool called decentralization and trustlessness. For example, when you graduate from university, the current practice is to have a certificate recognized and issued by an authoritative agency as your certificate. This setting is more troublesome, because this is a piece of paper, and paper can be forged, so there will be various gaps. The issuing authority is also a person, and there will be various gaps in the middle. As long as it is related to people, whoever There are various possibilities related to media. The blockchain provides a great opportunity. As soon as you graduate, you will have a record on the blockchain. No one can change this record. This thing exists objectively. You, as a physical existence , and then as a data existence, the blockchain was born. In this case, anyone who wants to check where you graduated can easily solve the problem. This is similar to the big data often involved in social networking (WeChat) and payment platforms (Alipay, Yibao).

Question 10: What does blockchain mean? Regarding blockchain, I think you have already seen the concept on the Internet. Let me explain it based on my understanding!
First, let’s talk about its characteristics: 1. Openness and transparency 2. Decentralization 3. Anonymity 4. Information cannot be tampered with and eliminated 5. No trust cost
Blockchain is like a public ledger , everyone has the right to record and read, and everyone will jointly supervise to ensure its accuracy, and the recorded content will be permanently saved, and can only be added but not deleted! However, as the number of blocks continues to increase, costs will increase and efficiency will decrease. (I’m not sure whether technology can be used to make up for this. I hope someone who understands technology can point it out.)
Blockchain is divided into public chain, private chain, and alliance chain. Public chain: accessible to everyone, everyone has read and write permissions, completely open, transparent and decentralized. Private chain: Open to individuals or institutions. The owner of the private chain can set various permissions to allow them toBecome partially centralized. Alliance chain: Open to specific organizations or groups, it is also "partially decentralized". According to the ledger at the beginning, members can view and transact, but cannot record and confirm bills, or require permission from the alliance. (The latter two do not have cost and efficiency issues)
Regarding blockchain, countries have begun to recruit talents in this area. For this, you can search online for "Central Bank Recruiting Digital Currency R&D Personnel". In addition, you can increase your understanding of blockchain by understanding its existing applications. What we usually refer to generally refers to public chains. Currently, those used abroad include Bitcoin, Ethereum and other domestic blockchains. Chain
1. Open and transparent: Every piece of data is verified by everyone and can be viewed by everyone at any time.
2. Decentralization: For example, when we shop on Taobao, we conduct transactions through the intermediary Taobao, and blockchain allows both supply and demand parties to directly contact each other for direct transactions through blockchain technology.
3. Anonymity: No personal privacy information is required to complete transactions on the blockchain, only your unique alphanumeric signature is required.
4. Information cannot be tampered with or deleted: Once the data has been verified and recorded, no one has the authority to modify it, let alone delete it!
5. No trust cost: The trust crisis in reality will not appear in the blockchain. Transactions in the blockchain do not require you to trust the other party. Only when both of you have enough "digital assets" to trade can it be carried out, and Under the supervision of the entire network, transactions will not be broken. If you have no idea about the cost of trust, just think about how many intermediaries there are in your city, or just think about Jack Ma, and you will know how big the cost of trust is.
I am still learning more about blockchain. I am Li Ailin. If you have any questions, you can discuss and learn together!

『撒』What does blockchain mean?

Blockchain is an important concept of Bitcoin. It is essentially a decentralized database that simultaneously operates Wu Zhibu is the underlying technology of Bitcoin. It is a series of data blocks generated using cryptographic methods. Each data block contains a batch of Bitcoin network transaction information, which is used to verify the validity of its information. (anti-counterfeiting) and generate the next block.

Blockchain is a new application model of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm.

2. In order to realize the great leap forward development of blockchain finance, in order to promote the new development of China’s economy, accelerate the circulation of global assets, and realize the renaissance that generations have been striving for. dream.
